Morningstar assigns star ratings based on our analysts' estimates of a stock's fair value. A 5-star stock is a good value at its current price; a 1-star stock isn't. Star ratings, which are updated daily, can change for three reasons: because analysts alter their estimate of a stock's fair value, because a

stock's price changes, or both. Ratings that change because analysts alter their estimate of a stock's fair value are marked with the symbol (*). Learn more about the Morningstar Rating for stocks here.Receive an e-mail alert when Stock Star Ratings change. Click to sign up.
